I was very intrigued with the idea of eating what was stated as a range between 1600-1700 calories per day and what was told to me is that this is calculated per my body's frame size and height. Also, this is for a sedentary person so I asked to give me the worst scenario and this was the calculations I was given. Both Dieticians didn't like me going down to 1200 calories thinking the energy level will drop, the fatigue feeling will set in and also that I couldn't do this long term. I was asking for permanent calories to sustain a 120-125 lb. perm. weight. What a different way to attempt to lose weight I thought.
